How can I validate route parameters in Vue.js using Vue Router?

You can validate route parameters in Vue.js by using route guards or by checking parameters in the component's lifecycle hooks.

Can you give me an example of using a route guard for validation?

Sure! You can use the beforeEnter guard in your route definition to validate parameters. For example:

const router = new VueRouter({
  routes: [
    {
      path: '/user/:id',
      component: User,
      beforeEnter: (to, from, next) => {
        const id = parseInt(to.params.id);
        if (isNaN(id) || id <= 0) {
          next({ path: '/error' }); // Redirect to error page
        } else {
          next(); // Proceed to the route
        }
      }
    }
  ]
});

What if I want to validate multiple parameters?

You can validate multiple parameters in the same beforeEnter guard by checking each parameter individually. Just add your validation logic for each one.
